You need a set of speedometer gears intended for 4.88 or 4.89 final drive.
They are certainly hard to come by.
Most but not all 4.88 applications were from 1954 to 1962 Willys P.U. and S.W.
Late 1962 -1964 S.W. and P.U. had 4.09 final drive with 230 Tornado engine.

You'll need both gears.
There are lots of Stewart Warner speedometer gear combinations.

I have all the D18 Stewart Warner part numbers somewhere.
The SW part numberr is stamped onto each gear.
I'll get that info when I can....

As stated a large variety of Stewart Warner (SW) speedometer gears were manufactured.
Various driven gears will only work with specific drive gears.
The SW part number is stamped onto every gear.
Various tire diameters were used on various models.
